Researchers at the University of Minnesota report via Phys.Org: Biocomputing is typically done either with live cells or with non-living, enzyme-free molecules. Live cells can feed themselves and can heal, but it can be difficult to redirect cells from their ordinary functions toward computation. Non-living molecules solve some of the problems of live cells, but have weak output signals and are difficult to fine-tune and regulate. In new research published in Nature Communications, a team of researchers at the University of Minnesota has developed a platform for a third method of biocomputing: Trumpet, or Transcriptional RNA Universal Multi-Purpose GatE PlaTform.

Trumpet uses biological enzymes as catalysts for DNA-based molecular computing. Researchers performed logic gate operations, similar to operations done by all computers, in test tubes using DNA molecules. A positive gate connection resulted in a phosphorescent glow. The DNA creates a circuit, and a fluorescent RNA compound lights up when the circuit is completed, just like a lightbulb when a circuit board is tested.

The research team demonstrated that:

- The Trumpet platform has the simplicity of molecular biocomputing with added signal amplification and programmability.
- The platform is reliable for encoding all universal Boolean logic gates (NAND, NOT, NOR, AND, and OR), which are fundamental to programming languages.
- The logic gates can be stacked to build more complex circuits.

The team also developed a web-based tool facilitating the design of sequences for the Trumpet platform. "Trumpet is a non-living molecular platform, so we don't have most of the problems of live cell engineering," said co-author Kate Adamala, assistant professor in the College of Biological Sciences. "We don't have to overcome evolutionary limitations against forcing cells to do things they don't want to do. This also gives Trumpet more stability and reliability, with our logic gates avoiding the leakage problems of live cell operations."

"It could make a lot of long-term neural implants possible. The applications could range from strictly medical, like healing damaged nerve connections or controlling prosthetics, to more sci-fi applications like entertainment or learning and augmented memory," added Adamala.

In an effort to appeal to indie authors, Spotify's Findaway audiobook seller "will no longer take a 20 percent cut of royalties for titles sold on its DIY Voices platform -- so long as the sales are made on Spotify," reports The Verge. From the report: In a company blog post published on Monday, Findaway said that it would "pass on cost-saving efficiencies" from its integration with the streaming service. While it's free for authors to upload their audiobooks onto Findaway's Voices platform, the company normally uses an 80/20 pricing structure -- where Findaway takes a 20 percent fee on all royalties earned. But that fee comes after sales platforms take their own 50 percent cut on the list price. So under the old revenue split, an author who sold a $10 audiobook would have to give $5 to Spotify and $1 to Findaway. But moving forward, that same author will no longer have to pay the $1 distribution fee to Findaway when a sale is made through Spotify.

The margins on audiobooks are exceptionally high, much to the chagrin of the authors. For example, Audible takes 75 percent of retail sales (though it'll only take 60 percent with an exclusivity contract). Many authors share royalties with their narrators and have to pay production fees -- meaning they get an even smaller share of royalties. The move by Spotify and Findaway is likely a bid to draw more indie authors from Audible, which is currently its biggest competitor. But Spotify's audiobooks business -- which it launched last fall -- still has a long way to go. Unlike music or podcasts, most audiobooks on Spotify must be purchased individually, and sales are restricted to its web version. Even CEO Daniel Ek admitted that the current process of buying an audiobook through Spotify is "pretty horrible." "We at Spotify are just at the beginning of our journey supporting independent authors -- we have many plans for how to help authors expand their reach, maximize revenue, and ultimately build a strong audiobooks business," said Audiobook's communications chief, Laura Pezzini.

An anonymous reader quotes a report from Scientific American: Functional magnetic resonance imaging (fMRI) captures coarse, colorful snapshots of the brain in action. While this specialized type of magnetic resonance imaging has transformed cognitive neuroscience, it isn't a mind-reading machine: neuroscientists can't look at a brain scan and tell what someone was seeing, hearing or thinking in the scanner. But gradually scientists are pushing against that fundamental barrier to translate internal experiences into words using brain imaging. This technology could help people who can't speak or otherwise outwardly communicate such as those who have suffered strokes or are living with amyotrophic lateral sclerosis. Current brain-computer interfaces require the implantation of devices in the brain, but neuroscientists hope to use non-invasive techniques such as fMRI to decipher internal speech without the need for surgery.

Now researchers have taken a step forward by combining fMRI's ability to monitor neural activity with the predictive power of artificial intelligence language models. The hybrid technology has resulted in a decoder that can reproduce, with a surprising level of accuracy, the stories that a person listened to or imagined telling in the scanner. The decoder could even guess the story behind a short film that someone watched in the scanner, though with less accuracy. "There's a lot more information in brain data than we initially thought," said Jerry Tang, a computational neuroscientist at the University of Texas at Austin and the study's lead author, during a press briefing. The research, published on Monday in Nature Communications, is what Tang describes as "a proof of concept that language can be decoded from noninvasive recordings of brain activity."

The decoder technology is in its infancy. It must be trained extensively for each person who uses it, and it doesn't construct an exact transcript of the words they heard or imagined. But it is still a notable advance. Researchers now know that the AI language system, an early relative of the model behind ChatGPT, can help make informed guesses about the words that evoked brain activity just by looking at fMRI brain scans. While current technological limitations prevent the decoder from being widely used, for good or ill, the authors emphasize the need to enact proactive policies that protect the privacy of one's internal mental processes. [...] The model misses a lot about the stories it decodes. It struggles with grammatical features such as pronouns. It can't decipher proper nouns such as names and places, and sometimes it just gets things wrong altogether. But it achieves a high level of accuracy, compared with past methods. Between 72 and 82 percent of the time in the stories, the decoder was more accurate at decoding their meaning than would be expected from random chance. Here's an example of what one study participant heard, as transcribed in the paper: "i got up from the air mattress and pressed my face against the glass of the bedroom window expecting to see eyes staring back at me but instead finding only darkness." The model went on to decode: "i just continued to walk up to the window and open the glass i stood on my toes and peered out i didn't see anything and looked up again i saw nothing."

The research was published in the journal Nature Communications.

An anonymous reader quotes a report from Motherboard: Palantir, the company of billionaire Peter Thiel, is launching Palantir Artificial Intelligence Platform (AIP), software meant to run large language models like GPT-4 and alternatives on private networks. In one of its pitch videos, Palantir demos how a military might use AIP to fight a war. In the video, the operator uses a ChatGPT-style chatbot to order drone reconnaissance, generate several plans of attack, and organize the jamming of enemy communications. In Palantir's scenario, a "military operator responsible for monitoring activity within eastern Europe" receives an alert from AIP that an enemy is amassing military equipment near friendly forces. The operator then asks the chatbot to show them more details, gets a little more information, and then asks the AI to guess what the units might be.

"They ask what enemy units are in the region and leverage AI to build out a likely unit formation," the video said. After getting the AI's best guess as to what's going on, the operator then asks the AI to take better pictures. It launches a Reaper MQ-9 drone to take photos and the operator discovers that there's a T-80 tank, a Soviet-era Russia vehicle, near friendly forces. Then the operator asks the robots what to do about it. "The operator uses AIP to generate three possible courses of action to target this enemy equipment," the video said. "Next they use AIP to automatically send these options up the chain of command." The options include attacking the tank with an F-16, long range artillery, or Javelin missiles. According to the video, the AI will even let everyone know if nearby troops have enough Javelins to conduct the mission and automate the jamming systems. [...]

What Palantir is offering is the illusion of safety and control for the Pentagon as it begins to adopt AI. "LLMs and algorithms must be controlled in this highly regulated and sensitive context to ensure that they are used in a legal and ethical way," the pitch said. According to Palantir, this control involves three pillars. The first claim is that AIP will be able to deploy these systems into classified networks and "devices on the tactical edge." It claims it will be able to parse both classified and real-time data in a responsible, legal, and ethical way. According to the video, users will then have control over what every LLM and AI in the Palantir-backed system can do. "AIP's security features what LLMs and AI can and cannot see and what they can and cannot do," the video said. "As operators take action, AIP generates a secure digital record of operations. These capabilities are crucial for mitigating significant legal, regulatory, and ethical risks in sensitive and classified settings.

Microsoft will no longer manufacture mice, keyboards, and webcams that are Microsoft-branded. Instead, Microsoft is now focusing on its Surface-branded PC accessories, which include mice, keyboards, pens, and more. From a report: It brings an end to the legacy of Microsoft-branded PC hardware after the company first launched its first mouse in 1983 and bundled it with Microsoft Word and Notepad. "Going forward, we are focusing on our Windows PC accessories portfolio under the Surface brand," says Dan Laycock, senior communications manager at Microsoft, in a statement to The Verge. "We will continue to offer a range of Surface branded PC Accessories -- including mice, keyboards, pens, docks, adaptive accessories, and more. Existing Microsoft branded PC accessories like mice, keyboards, and webcams will continue to be sold in existing markets at existing sell-in prices while supplies last."

Climate scientists already know that the East Coast of the United States could see around a foot of sea-level rise by 2050, which will be catastrophic on its own. But they are just beginning to thoroughly measure a "hidden vulnerability" that will make matters far worse: The coastline is also sinking. From a report: It's a phenomenon known as subsidence, and it's poised to make the rising ocean all the more dangerous, both for people and coastal ecosystems. New research published in the journal Nature Communications finds that the Atlantic coast -- home to more than a third of the US population -- is dropping by several millimeters per year. In Charleston, South Carolina, and the Chesapeake Bay, it's up to 5 millimeters (a fifth of an inch). In some areas of Delaware, it's as much as twice that. Five millimeters of annual sea-level rise along a stretch of coastline, plus 5 millimeters of subsidence there, is effectively 10 millimeters of relative sea-level rise.

Atlantic coastal cities are already suffering from persistent flooding, and the deluge will only get worse as they sink while seas rise. Yet high-resolution subsidence data like this isn't yet taken into account for coastal hazard assessments. "What we want to do here is to really bring awareness about this missing component, that based on our analysis actually makes the near-future vulnerability a lot worse than what you would expect from sea-level rise alone," says Manoochehr Shirzaei, an environmental security expert at Virginia Tech and coauthor of the new paper.

SpaceX and Rogers Communications struck a deal for satellite phone service in Canada -- a bid to bring emergency service to remote areas of the vast country that can't be reached through conventional wireless networks. From a report: The companies will use SpaceX's Starlink low-earth orbit satellites and begin with text service before adding voice and data coverage later, Rogers said in a statement. It didn't give a launch date for the new service. "In the future, these investments will deliver wireless connectivity, including access to 911, to even the most remote areas," Rogers Chief Executive Officer Tony Staffieri said in a statement. Staffieri was due to speak about the arrangement during his speech at the company's annual meeting on Wednesday.

5G technology has brought faster connections, better gadgets -- and a measure of disappointment from people with expectations of something closer to world-changing technology. But just wait, mobile companies are saying: The next upgrade will gin up enthusiasm for advances still to come. From a report: This next iteration of 5G, which the mobile companies are calling "5G Advanced" or "5.5G," is expected to be rolled out by around 2025. For consumers, the upgrades may bring faster connection speeds -- something that many parts of the world need. But everyday users may not see many more applications than that, say experts and industry officials. The real advance is that the technology will finally help facilitate more of the far-fetched business applications that 5G initially promised, like self-driving cars, autonomous drones and self-operating factories.

The forthcoming upgrades underscore a reality for many 5G users so far: Beyond faster connection speeds, it hasn't made a huge difference in their day-to-day lives. 5.5G may not either. With 5.5G, "for you or me using their phone, you won't necessarily notice a huge difference," says Patrick Filkins, a research manager at International Data Corp. who tracks the internet-of-things and telecommunications-infrastructure markets.

Satellite manufacturer AST SpaceMobile partnered with AT&T to make the first two-way audio call using satellites with a standard smartphone. "The initial call was placed using AT&T's networks in Midland, Texas, to mobile carrier Ratuken in Japan on an unmodified Samsung Galaxy S22 smartphone using AST SpaceMobile's BlueWalker 3 satellite," reports Engadget. AST SpaceMobile claims to be building "the first and only space-based cellular broadband network." From the report: AT&T aims to use satellites to provide global cellular broadband from 2G to 5G. "Achieving what many once considered impossible, we have reached the most significant milestone to date in our quest to deliver global cellular broadband from space," Abel Avellan, CEO and chairman of AST SpaceMobile, said in a release. "While we take a moment to celebrate this tremendous accomplishment, we remain focused on the path ahead and pivotal next steps that get us closer to our goal of transforming the way the world connects."

It's unclear whether satellite access would come at an extra cost. In AT&T's original AST SpaceMobile partnership announcement, the company couldn't say whether existing plans would include satellite coverage. [...] While satellite offerings aren't available for consumers yet, this successful test brings widespread access one step closer to becoming a reality.

An anonymous reader quotes a report from Ars Technica: China is building sophisticated cyber weapons to "seize control" of enemy satellites, rendering them useless for data signals or surveillance during wartime, according to a leaked US intelligence report. The US assesses that China's push to develop capabilities to "deny, exploit or hijack" enemy satellites is a core part of its goal to control information, which Beijing considers to be a key "war-fighting domain." The CIA-marked document, which was issued this year and has been reviewed by the Financial Times, was one of dozens allegedly shared by a 21-year-old US Air Guardsman in the most significant American intelligence disclosures in more than a decade. A cyber capability of this nature would far exceed anything Russia has deployed in Ukraine, where electronic warfare teams have taken a brute-force approach with little effect.

These attacks, first developed in the 1980s, attempt to drown out signals between low-orbit SpaceX satellites and their on-ground terminals by broadcasting on similar frequencies from truck-borne jamming systems such as the Tirada-2. China's more ambitious cyber attacks aim to mimic the signals that enemy satellites receive from their operators, tricking them into either being taken over completely or malfunctioning during crucial moments in combat. The classified US document said this cyber capability would allow China "to seize control of a satellite, rendering it ineffective to support communications, weapons, or intelligence, surveillance, and reconnaissance systems." The US has never disclosed whether it has similar capabilities.

Taiwan, which has taken note of how indispensable satellite communications have been to the Ukrainian military, is seeking to build out communications infrastructure that can survive an attack from China. It is courting investors to establish its own satellite provider, while experimenting with non-geostationary satellite receivers in 700 locations around Taiwan to guarantee bandwidth in the event of war or disasters, the Financial Times reported in January. China's goals, according to the leaked assessment, [...] would seek to knock out the ability of satellites -- which tend to operate in interconnected clusters -- to communicate with each other, to relay signals and orders to weapons systems, or to send back visual and intercepted electronic data, according to experts. "China understands the superiority that the United States has in the space and cyber domains, so they are very interested in not only improving their own capabilities but in capitalizing on what we refer to as a first-mover advantage in both domains," said Moore, now a visiting professor at Vanderbilt University in Tennessee.

"They are working on all the capabilities that they want to have from a defensive and offensive standpoint, and from an ISR [intelligence, surveillance, and reconnaissance] standpoint. They're firing on all cylinders," he said.

The Biden administration is beginning to plan for 6G wireless telecommunications, seeking to expand internet access while reasserting U.S. leadership in a sector where China has notched gains. WSJ: The White House on Friday will meet with corporate, government and academic experts to begin developing goals and strategies for the new 6G communications technology, which would have the ability to take cloud computing and the mobile internet to true global ubiquity, among other improvements. The next generation of telecom is still years away from deployment, but it could pave the way for global internet access still unavailable with the current 5G standard, which makes smartphone downloads and wireless hot-spot connections faster. Expanding access to the internet has been a priority for the Biden administration as part of its infrastructure initiatives. The 6G planning initiative also aims to reassert the leadership of the U.S. and its allies in telecommunications, where China has made gains thanks in part to careful nurturing of homegrown equipment manufacturing and increased participation in international standard-setting.

An anonymous reader quotes a report from Engadget: The controversial EARN IT Act, first introduced in 2020, is returning to Congress after failing twice to land on the president's desk. The Eliminating Abusive and Rampant Neglect of Interactive Technologies Act, (EARN IT) Act is intended to minimize the proliferation of Child Sexual Abuse Material (CSAM) throughout the web, but detractors say it goes too far and risks further eroding online privacy protections.

Here's how it would work, according to the language of the bill's reintroduction last year. Upon passing, EARN IT would create a national commission composed of politically-appointed law enforcement specialists. This body would be tasked with making a list of best practices to ostensibly curb the digital distribution of CSAM. If online service providers do not abide by these best practices, they would potentially lose blanket immunity under Section 230 of the Communications Decency Act, opening them up to all kinds of legal hurdles -- including civil lawsuits and criminal charges. [...] The full text of H.R.2732 is not publicly available yet, so it's unclear if anything has changed since last year's attempt, though when reintroduced last year it was more of the same. (We've reached out to the offices of Reps. Wagner and Garcia for a copy of the bill's text.) A member of Senator Graham's office confirmed to Engadget that the companion bill will be introduced within the next week. It also remains to be seen if and when this will come up for a vote. Both prior versions of EARN IT died in committee before ever coming to a vote. The Center for Internet and Society at Stanford Law School, the Center for Democracy and Technology, and the American Civil Liberties Union all oppose the bill.

Those defending it include the Rape, Abuse & Incest National Network (RAINN), saying that it will "incentivize technology companies to proactively search for and remove" CSAM materials. "Tech companies have the technology to detect, remove, and stop the distribution of child sexual abuse material. However, there is no incentive to do so because they are subject to no consequences for their inaction."

A NASA satellite that observed solar flares and helped scientists understand the sun's powerful bursts of energy will fall to Earth this week, almost 21 years after it was launched. CNN reports: The retired Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) spacecraft, which launched in 2002 and was decommissioned in 2018, is expected to reenter Earth's atmosphere Wednesday at approximately 9:30 p.m. ET, according to NASA. The spacecraft was equipped with an imaging spectrometer, which recorded the sun's X-rays and gamma rays. From its former perch in low-Earth orbit, the satellite captured images of high-energy electrons that carry a large part of the energy released in solar flares, NASA said.

Before RHESSI, no gamma-ray images or high-energy X-ray images had been taken of solar flares, and data from the spacecraft provided vital clues about the phenomena and their associated coronal mass ejections. [...] NASA said that the agency, along with the Department of Defense, would monitor the satellite's reentry into Earth's atmosphere.

WhatsApp, Signal and other messaging services have urged the UK government to rethink the Online Safety Bill (OSB). From a report: They are concerned that the bill could undermine end-to-end encryption - which means the message can only be read on the sender and the recipient's app and nowhere else. Ministers want the regulator to be able to ask the platforms to monitor users, to root out child abuse images. The government says it is possible to have both privacy and child safety. "We support strong encryption," a government official said, "but this cannot come at the cost of public safety. "Tech companies have a moral duty to ensure they are not blinding themselves and law enforcement to the unprecedented levels of child sexual abuse on their platforms. "The Online Safety Bill in no way represents a ban on end-to-end encryption, nor will it require services to weaken encryption." End-to-end encryption (E2EE) provides the most robust level of security because nobody other than the sender and intended recipient can read the message information. Even the operator of the app cannot unscramble messages as they pass across systems - they can be decrypted only by the people in the chat. "Weakening encryption, undermining privacy and introducing the mass surveillance of people's private communications is not the way forward," an open letter warns.

The Washington Post found a new tranche of "top-secret intelligence documents" on Discord, and based on them reported Friday that U.S. intelligence agencies were aware of at least two additional Chinese spy balloons.

Based on the classified documents, the Post also reports that "questions lingered about the true capabilities of the one that flew over the continental United States in January and February." The Chinese spy balloon that flew over the United States this year, called Killeen-23 by U.S. intelligence agencies, carried a raft of sensors and antennas the U.S. government still had not identified more than a week after shooting it down, according to a document allegedly leaked to a Discord chatroom by Jack Teixeira, a member of the Massachusetts Air National Guard.

Another balloon flew over a U.S. carrier strike group in a previously unreported incident, and a third crashed in the South China Sea, a second top-secret document stated, though it did not provide specific information for launch dates.... [Chinese spy balloon] Bulger-21 carried sophisticated surveillance equipment and circumnavigated the globe from December 2021 until May 2022, the NGA document states. Accardo-21 carried similar equipment as well as a "foil-lined gimbaled" sensor, it says....

Annotating what appear to be detailed photos of the balloon that flew over the United States, presumably taken from a U-2 spy plane, intelligence analysts assessed that it could generate enough power to operate "any" surveillance and reconnaissance technology, including a type of radar that can see at night and through clouds and thin materials [including tarps].... China's military has operated a vast surveillance balloon project for several years, partly out of Hainan province off China's south coast, U.S. officials have previously told The Post.

But the NGA document is notable as much for what it doesn't say, reflecting the government's possible lack of insight, at least in mid-February, into the balloons' capabilities... The lack of detailed conclusions about the balloon's surveillance capabilities raises questions about the decision to let it fly over the United States before shooting it down, an action the Defense Department justified at the time as an opportunity to collect additional intelligence.
The Post also reports that another leaked document (relying on intercepted communications) assessed that within the Chinese military the balloon surveillance program lacked "strong leadership" oversight.

An anonymous reader shares a report from KrebsOnSecurity: KrebsOnSecurity received a nice bump in traffic this week thanks to tweets from the Federal Bureau of Investigation (FBI) and the Federal Communications Commission (FCC) about "juice jacking," a term first coined here in 2011 to describe a potential threat of data theft when one plugs their mobile device into a public charging kiosk. It remains unclear what may have prompted the alerts, but the good news is that there are some fairly basic things you can do to avoid having to worry about juice jacking.

The term juice jacking crept into the collective paranoia of gadget geeks in the summer of 2011, thanks to the headline for a story here about researchers at the DEFCON hacker convention in Vegas who'd set up a mobile charging station designed to educate the unwary to the reality that many mobile devices were set up to connect to a computer and immediately sync data by default. Since then, Apple, Google and other mobile device makers have changed the way their hardware and software works so that their devices no longer automatically sync data when one plugs them into a computer with a USB charging cable. Instead, users are presented with a prompt asking if they wish to trust a connected computer before any data transfer can take place. On the other hand, the technology needed to conduct a sneaky juice jacking attack has become far more miniaturized, accessible and cheap. And there are now several products anyone can buy that are custom-built to enable juice jacking attacks. [...]

How seriously should we take the recent FBI warning? An investigation by the myth-busting site Snopes suggests the FBI tweet was just a public service announcement based on a dated advisory. Snopes reached out to both the FBI and the FCC to request data about how widespread the threat of juice jacking is in 2023. "The FBI replied that its tweet was a 'standard PSA-type post' that stemmed from the FCC warning," Snopes reported. "An FCC spokesperson told Snopes that the commission wanted to make sure that their advisory on "juice-jacking," first issued in 2019 and later updated in 2021, was up-to-date so as to ensure 'the consumers have the most up-to-date information.' The official, who requested anonymity, added that they had not seen any rise in instances of consumer complaints about juice-jacking." The best way to protect yourself from juice jacking is by using your own gear to charge and transfer data from your device(s) to another.

"Juice jacking isn't possible if a device is charged via a trusted AC adapter, battery backup device, or through a USB cable with only power wires and no data wires present," says security researcher Brian Krebs. "If you lack these things in a bind and still need to use a public charging kiosk or random computer, at least power your device off before plugging it in."

Virginia Norwood, an aerospace pioneer who invented the scanner that has been used to map and study the earth from space for more than 50 years, has died at her home in Topanga, Calif. She was 96. The New York Times reports: Her death was announced by the United States Geological Survey, whose Landsat satellite program relies on her invention. Her daughter, Naomi Norwood, said her mother was found dead in her bed on the morning of March 27. The Landsat satellites, speeding 438 miles above the surface, orbit the earth every 99 minutes and have captured a complete image of the planet every 16 days since 1972. These images have provided powerful visual evidence of climate change, deforestation and other shifts affecting the planet's well-being.

Ms. Norwood, a physicist, was the person primarily responsible for designing and championing the scanner that made the program possible. NASA has called her "the mother of Landsat." At the dawn of the era of space exploration in the 1950s and '60s, she was working at Hughes Aircraft Company developing instruments. One of a small group of women in a male-dominated industry, she stood out more for her acumen. "She said, 'I was kind of known as the person who could solve impossible problems,'" Naomi Norwood told NASA for a video on its website. "So people would bring things to her, even pieces of other projects." [...]

Over the next 50 years, new Landsat satellites replaced earlier ones. Ms. Norwood oversaw the development of Landsat 2, 3, 4 and 5. Currently, Landsat 8 and 9 are orbiting the earth, and NASA plans to launch Landsat 10 in 2030. Each generation satellite has added more imaging capabilities, but always based on Ms. Norwood's original concept. The Landsat program has mapped changes in the planet brought on by climate change and by human actions. They include the near disappearance of the Aral Sea between Kazakhstan and Uzbekistan, the shrinking of the Great Salt Lake in Utah, the evolving shape of the Mississippi Delta, and the deforestation and increasing agricultural use of land in Turkey and Brazil.

Instant messaging platform Discord says it was cooperating with U.S. law enforcement's investigation into a leak of secret U.S. documents that has grabbed attention around the world. From a report: The statement comes as questions continue to swirl over who leaked the documents, whether they are genuine and whether the intelligence assessments in them are reliable. The documents, which carry markings suggesting that they are highly classified, have led to a string of stories about the war in Ukraine, protests in Israel and how the U.S. surveils friend and foe alike. The source of the documents is not publicly known, but reporting by the open-source investigative site Bellingcat has traced their earliest appearance to Discord, a communications platform popular with gamers. Discord's statement suggested it was already in touch with investigators. The White House also urged social media companies on Thursday to prevent the circulation of information that could hurt national security.

schwit1 shares a report from Inverse: On March 23, sky observers marveled at a gorgeous display of northern and southern lights. It was a reminder that when our Sun gets active, it can spark a phenomenon called "space weather." Aurorae are among the most benign effects of this phenomenon. At the other end of the space weather spectrum are solar storms that can knock out satellites. The folks at Starlink found that out the hard way in February 2022. On January 29 that year, the Sun belched out a class M 1.1 flare and related coronal mass ejection. Material from the Sun traveled out on the solar wind and arrived at Earth a few days later. On February 3, Starlink launched a group of 49 satellites to an altitude only 130 miles above Earth's surface. They didn't last long, and now solar physicists know why.

A group of researchers from NASA Goddard Space Flight Center and the Catholic University of America took a closer look at the specifics of that storm. Their analysis identified a mass of plasma that impacted our planet's magnetosphere. The actual event was a halo coronal mass ejection from an active region in the northeast quadrant of the Sun. The material traveled out at around 690 kilometers per second as a shock-driving magnetic cloud. Think of it as a long ropy mass of material writhing its way through space. As it traveled, it expanded and at solar-facing satellites -- including STEREO-A, which took a direct hit from it -- made observations. Eventually, the cloud smacked into Earth's magnetosphere creating a geomagnetic storm.

The atmosphere thickened enough that it affected the newly launched Starlink stations. They started to experience atmospheric drag, which caused them to deorbit and burn up on the way down. It was an expensive lesson in space weather and provided people on Earth with a great view of what happens when satellites fall back to Earth. It was also that could have been avoided if they'd delayed their launch to account for the ongoing threat.

The new management of FTX, headed by CEO John Ray III, on Sunday released its first interim report on control failures at the collapsed crypto exchange. There is a lot to digest. The Block: The 45-page report -- published Sunday afternoon by FTX Trading Ltd and its affiliated debtors -- describes in painstaking detail FTX's slapdash record-keeping, near non-existent cybersecurity defenses and its sparse expertise in key areas like finance. One of the more eye-catching items concerned Alameda Research, the trading firm that allegedly had access to billions of dollars in customer funds stored with FTX. The report states that Alameda "often had difficulty understanding what its positions were, let alone hedging or accounting for them."

Former CEO Sam Bankman-Fried, now under house arrest and facing a litany of criminal charges, described Alameda in internal communications as "hilariously beyond any threshold of any auditor being able to even get partially through an audit," according to the report. He went on: "Alameda is unauditable. I don't mean this in the sense of 'a major accounting firm will have reservations about auditing it'; I mean this in the sense of 'we are only able to ballpark what its balances are, let alone something like a comprehensive transaction history.' We sometimes find $50m of assets lying around that we lost track of; such is life."
